Disclosed are a method for arranging main and lateral reciprocating teeth on a jack section-increasing tooth body and a mining machine with main and lateral reciprocating teeth arranged on a section-increasing tooth body in a jack manner, which relate to the field of mining machines. The mining machine comprises an integrated block sealing guiding and rotation stopping box (1), a linked guiding sealing tooth socket (3), main reciprocating teeth (4) and lateral reciprocating teeth (5), wherein the main reciprocating teeth (4) are provided with the lateral reciprocating teeth (5), when an insertion-column section-increasing tooth body (17) is arranged, one end of a tooth-holder main tooth body (18) is provided with a main reciprocating tooth jack (20) or provided with a main reciprocating tooth insertion column (8), the other end is provided with a section-increasing tooth body jack (26) or provided with a section-increasing tooth body insertion column (21), the insertion-column section-increasing tooth body (17) is correspondingly provided with a section-increasing tooth body column (22) or a section-increasing tooth body hole (23), the section-increasing tooth body column (22) is inserted into a section-increasing tooth body insertion hole (24) or the section-increasing tooth body hole (23) is in register with the section-increasing tooth body insertion column (21), and when a cascading-type section-increasing tooth body (27) is arranged, inner holes of two or more than two fixed lateral tooth rings (30) are in register with the periphery of a pin-type main tooth body (28), so that the height for arranging a lateral tooth head (14) is increased. The mining machine increases a mining height and a mining width of a coal mining machine and a heading machine and is safe and reliable. |
